Embodiment Construction

[0015] Specific embodiments of the present invention will be described in detail below.

[0016] Add 100 mol of aminomethylcyclopentylamine and 100±10 mol of butyl glycidyl ether in the installed enamel glass reaction kettle, metering tank, vacuum pump, dry nitrogen protection and other devices at room temperature; replace the air in the reaction kettle with nitrogen , start stirring and raise the temperature to 50°C at the same time, control the temperature at 50-90°C, and control the reaction temperature by passing cooling water during the feeding process. Maintain 90°C for 90 minutes, cool down to 35°C and pack. Dry nitrogen filled the remainder of the autoclave throughout the reaction.

[0017] According to above-mentioned method and formula, the performance that obtains product is as follows:

[0018] Appearance Colorless or light yellow flowing liquid

[0019] Viscosity 10~25s (coat 4 cups)

[0020] Amine equivalent 100~130g / mol

[0021] Active hydrogen equivalent 8...

Abstract

The invention is an alicyclic amine modified epoxy resin hardener, using aminomethyl cyclopentamine as material for modification. Its characteristic: it is synthesized of epoxy resin active diluting agents like aminomethyl cyclopentamine, alkyl alcohol glycidyl ether/organic acid glycidic ester, etc, and/or small molecular weight epoxy resin, and other raw materials. The hardener has moderate active hydrogen equivalent, low viscosity, and hardens at normal temperature, and the hardening course has the characters of low heat release, no toxic and excitive volatile, being uneasy to absorb moisture and blush, good compatibility with the epoxy resin, condensate with light colors and even colorless, etc, and it is an environmental protection hardener. It shows very good performance as used in self-leveling coating and ordinary floor coating, electronic sealing material, handicraft decoration, etc.

Description

technical field [0001] The invention belongs to the field of epoxy resin curing materials, and relates to the application of epoxy resin-based adhesives, coatings, potting materials, decorations, etc., and the specific content is alicyclic amine modified epoxy resin curing agent and its preparation method. Background technique [0002] There are many types of epoxy resin curing agents used for bonding, potting and coating at room temperature, usually belonging to organic aliphatic amines or their modified products, with simple bonding process, excellent bonding strength, small shrinkage, and mechanical properties , dielectric properties, good chemical stability, etc., but there are easy to change color, moisture absorption, whitening, irritating volatiles, and some even add environmental pollution and threat to human health due to high viscosity or system requirements. Organic solvents are used as diluents; for floor coating topcoats and handicraft decoration, not only high...
